Another lame buzzword you don't need to worry about, invented and promoted by people who want to give the impression of having some special insight that you don't have.

The web is what it is and new developments happen incrementally in a way not suited to version numbers. These buzzwords are for try-hards.

Good points. Just like most folks, I am wondering when Web2.0 officially came about. I believe the line of demarcation is when sites truly became interactive and allowed visitors to interact with the sites.

Web3.0? Who knows, maybe the web will scratch my back while I'm surfing.
